It was a fork of moment-jalali but the main goal of this repository is to facilitate converting any library using moment.js to be compatible with jalali calendar system. List of packages use jalali-moment to convert calendar system.

Please take a look at day.js, jalaliday module.

How to

  • Install

  • Use jalali moment in

  • Use API

    This plugin provides using jalali and gregorian calendar system together on momentjs api.

    .locale('fa'); it will use jalali calendar system

    .locale('any other locale'); it will use gregorian calendar system

    You can set locale for a moment instance(locally) or set it globally example of changing locale locally

    const m = moment();
    m.format('YY-MM-DD'); // it would be in jalali system

    change locale globally

    moment().format();// it would be in jalali system
    moment().add(1,'m').format();// it would be in jalali system

    Notice : When you need parse a date which is not in the system you have set for global locale you can use of method moment.from(date, 'another locale')

    moment.from('2018-04-04', 'en', 'YYYY-MM-DD').format();// it would be in jalali system

    When locale is globally set to 'fa', it's also possible to use gregorian calendar for parsing a date. By setting { useGregorianParser: true } as second parameter of .locale() you can reach this. useGregorianParser default value is false in 'fa' locale.

    moment.locale('fa', { useGregorianParser: true });  
    moment('2018-04-04').format();// it would be in jalali system  
    moment('2019-01-17T08:19:19.975Z').format();// it would be in jalali system  


  • Parse
    // parse gregorian date
    m = moment('1989/1/24', 'YYYY/M/D');// parse a gregorian (miladi) date
    m = moment.from('01/1989/24', 'en', 'MM/YYYY/DD');
    // parse jalali date
    m = moment('1367/11/04', 'jYYYY/jMM/jDD');
    m = moment.from('1367/04/11', 'fa', 'YYYY/MM/DD');
    m = moment.from('04/1367/11', 'fa', 'DD/YYYY/MM');
  • Display
    m.format('jYYYY/jMM/jDD'); // 1367/11/04
    m.locale('fa').format('YYYY/MM/DD'); // 1367/11/04
  • Manipulate
    m.add(1, 'day').locale('fa').format('YYYY/MM/DD'); // 1367/11/05
  • Validate
    m.isSame(m.clone()); // true
  • Convert
    moment.from('1367/11/04', 'fa', 'YYYY/MM/DD').format('YYYY/MM/DD'); // 1989/01/24
    moment('1989/01/24', 'YYYY/MM/DD').locale('fa').format('YYYY/MM/DD'); // 1367/11/04


jalali(Persian) calendar is a solar calendar system. It gains approximately 1 day on the Julian calendar every 128 years. Read more on Wikipedia.

Calendar conversion is based on the algorithm provided by Kazimierz M. Borkowski and has a very good performance.

This plugin adds Jalali (Persian, Khorshidi, Shamsi) calendar system to moment.js library.


Install via npm

npm install jalali-moment -S

Install via yarn

yarn add jalali-moment

Install via bower

bower install jalali-moment --save

Using in Node.js

Install it via npm or yarn then use it as the following code

var moment = require('jalali-moment');

Using in browser


get library using bower, npm, cdn, or cloning the repository

<!--<script src="bower_components/jalali-moment/dist/jalali-moment.browser.js"></script>-->
<!--<script src="node_modules/jalali-moment/dist/jalali-moment.browser.js"></script>-->
<script src="https://unpkg.com/jalali-moment/dist/jalali-moment.browser.js"></script>
<!--<script src="thisRepositoryPath/dist/jalali-moment.browser.js"></script>-->



import moment from 'jalali-moment'
render() {
    return (
            this.props.data.map((post,key) =>
                <div key={key} className='post-detail'>
                    <p>{moment(post.date, 'YYYY/MM/DD').locale('fa').format('YYYY/MM/DD')}</p>
                    <hr />


import * as moment from 'jalali-moment';
let todayJalali = moment().locale('fa').format('YYYY/M/D');


import * as moment from 'jalali-moment';

Add a pipe

  name: 'jalali'
export class JalaliPipe implements PipeTransform {
  transform(value: any, args?: any): any {
    let MomentDate = moment(value, 'YYYY/MM/DD');
    return MomentDate.locale('fa').format('YYYY/M/D');

and use it in component template

 <div>{{ loadedData.date | jalali }}</div>


You can create a value converters like following:

import { valueConverter } from 'aurelia-framework';
var moment = require('jalali-moment');

export class DateValueConverter {
  toView(value: string, format: string = 'YYYY/MM/DD', locale: string = 'en') {
    if (!value) return null;
    return moment(value, 'YYYY/MM/DD').locale(locale).format(format);

then use this value converter in your html files:

<require from="path_to_your_date_value_converter"></require>

<h1 style="direction:ltr">

also, for aurelia developers, there is a plugin, aurelia-time, in which there are value converters for jalali-moment and other time and date libraries.


Use vue-jalali-moment library

<span>{{ someDate | moment('dddd, MMMM Do YYYY') }}</span>

Command Line

Its cli needs to get installed globally

npm i -g jalali-moment

Then you will be able to convert Persian date to Gregorian and vice versa in terminal or command line as the following

jalalim tojalali 1989/1/24
jalalim togregorian 1392/5/8

This plugin tries to change calendar system moment.js api by using locale method.

now = moment(); //get the current date and time,


Create a instance of moment from a Jalali (Persian) or Miladi date and time as string.more

gregorian date
m = moment('1989/1/24', 'YYYY/M/D');
m = moment.from('1989/1/24', 'en', 'YYYY/M/D');
m = moment.from('01/1989/24', 'en', 'MM/YYYY/DD');
persian date
m = moment('1367/11/4', 'jYYYY/jM/jD');
m = moment.from('1367/11/04', 'fa', 'YYYY/MM/DD');
m = moment.from('11/1367/04', 'fa', 'MM/YYYY/DD');

// it will change locale for all new moment instance
m = moment('1367/11/04', 'YYYY/M/D');

Display jalali or miladi date

Display moment instance as a string.more

moment.locale('en'); // default locale is en
m = moment('1989/1/24', 'YYYY/M/D');
m.locale('fa'); // change locale for this moment instance
m.format('YYYY/M/D');// 1367/11/4
m.format('MM'); // 11 display jalali month
m.format('MMMM'); // Bahman
m.format('DD'); // 04 display day by two digit

m.format('w'); // 45 display week of year
m.format('M'); // 1 display miladi month
m.format('MM'); // 01 display month by two digit
m.format('MMMM'); // January
m.format('jYYYY/jM/jD [is] YYYY/M/D'); // 1367/11/4 is 1989/1/24


There are a number of methods to modify date and time.more

m.year(1368); // set jalali year
//  If the range is exceeded, it will bubble up to the year.
m.month(3); // month will be 4 and m.format('M')=='4' , jMonth Accepts numbers from 0 to 11.
m.date(10); // set a date
m.format('YYYY/MM/D'); // 1368/4/10
m.subtract(1, 'year'); // subtract a Jalali Year
m.format('YYYY/MM/D'); // 1367/4/10

m.format('YYYY/MM/D'); // 1367/6/10
m.endOf('month').format('YYYY/MM/D'); // 1367/6/31
m.startOf('year').format('YYYY/MM/D'); // 1367/1/1


Check a date and time.more

m = moment('1367/11/4', 'jYYYY/jM/jD');
m.isLeapYear(); // false
m.isSame(moment('1989-01-01','YYYY-MM-DD'), 'year'); // true
m.isSame(moment('1367-01-01','jYYYY-jMM-jDD'), 'year'); // true

m.isAfter(moment('1367-01-01','jYYYY-jMM-jDD'), 'jyear'); // false
m.isValid(); // true
moment('1396/7/31' ,'jYYYY/jM/jD').isValid(); // false
